As shown in FIG. 1, the display apparatus 10 may include a main body 11,a screen 12 for displaying an image I, and a support 103 provided at alower portion of the main body 11 to support the main body 11.

The main body 11 may form an outer appearance of the display apparatus10, and components for enabling the display apparatus 10 to display theimage I or perform various functions may be installed inside the mainbody 11. The main body 11 shown in FIG. 1 may be in a shape of a flatplate. However, the shape of the main body 11 is not limited to thatshown in FIG. 1. For example, the main body 11 may be in a shape of acurved plate.

The screen 12 may be formed on a front surface of the main body 11 anddisplay an image I. For example, the screen 12 may display a still imageor a moving image. Also, the screen 12 may display a 2-Dimensional (2D)planar image or a 3-Dimensional (3D) stereoscopic image using a user'sbinocular eyes.

On the screen 12, a plurality of pixels P may be formed, and the image Idisplayed on the screen 12 may be formed by light emitted from theplurality of pixels P. For example, light emitted from the plurality ofpixels P may be combined into a mosaic, and formed as the image I on thescreen 12.

The plurality of pixels P may emit light having various brightnesslevels and various colors. For example, each of the plurality of pixelsP may include a self-emissive panel (for example, a Light Emitting Diode(LED) panel) capable of itself emitting light, or a non-emissive panel(for example, a Liquid Crystal Display (LCD) panel) capable oftransmitting or blocking light emitted by a light source device.

The sub pixels may include a red sub pixel P_(R) capable of emitting redlight, a green sub pixel P_(G) capable of emitting green light, and ablue sub pixel P_(B) capable of emitting blue light. For example, redlight may correspond to light of a wavelength range from about 620 nm(nanometer, one billionth of a meter) to about 750 nm, green light maycorrespond to light of a wavelength range from about 495 nm to about 570nm, and blue light may correspond to light of a wavelength range fromabout 450 nm to about 495 nm.

By a combination of red light from the red sub pixel P_(R), green lightfrom the green sub pixel P_(G) and blue light from the blue sub pixelP_(B), the plurality of pixels P may emit light of various brightnesslevels and various colors.

As shown in FIG. 2, various components for generating the image I on thescreen 12 may be installed inside the main body 11.

For example, the main body 11 may include a light source device 100which is a surface light source, a liquid crystal panel 20 for blockingor transmitting light emitted from the light source device 100, acontrol assembly 50 for controlling operations of the light sourcedevice 100 and the liquid crystal panel 20, and a power supply assembly60 for supplying power to the light source device 100 and the liquidcrystal panel 20. Also, the main body 11 may include a bezel 13, a framemiddle mold 14, a bottom chassis 15, and a rear cover 16 for supportingand fixing the liquid crystal panel 20, the light source device 100, thecontrol assembly 50, and the power supply assembly 60.

The light source device 100 may include a point light source foremitting monochromatic light or white light, and may refract, reflect,and scatter light to convert light emitted from the point light sourceinto uniform surface light. For example, the light source device 100 mayinclude a plurality of light sources for emitting monochromatic light orwhite light, a diffuser plate for diffusing light emitted from theplurality of light sources, a reflective sheet for reflecting lightemitted from the plurality of light sources and a rear surface of thediffuser plate, and an optical sheet for refracting and scattering lightemitted from a front surface of the diffuser plate.

As such, the light source device 100 may emit uniform surface lighttoward a front direction by refracting, reflecting, and scattering lightemitted from the light sources.

A configuration of the light source device 100 will be described in moredetail below.

The liquid crystal panel 20 may be positioned in front of the lightsource device 100, and block or transmit light emitted from the lightsource device 100 to form an image I.

A front surface of the liquid crystal panel 20 may form the screen 12 ofthe display apparatus 10 described above, and the liquid crystal panel20 may form the plurality of pixels P. The plurality of pixels P of theliquid crystal panel 20 may independently block or transmit light of thelight source device 100, and light transmitted through the plurality ofpixels P may form an image I that is displayed on the screen 12.

For example, as shown in FIG. 3, the liquid crystal panel 20 may includea first polarizing film 21, a first transparent substrate 22, a pixelelectrode 23, a thin film transistor (TFT) 24, a liquid crystal layer25, a common electrode 26, a color filter 27, a second transparentsubstrate 28, and a second polarizing film 29.

The first transparent substrate 22 and the second transparent substrate28 may fix and support the pixel electrode 23, the thin film transistor24, the liquid crystal layer 25, the common electrode 26, and the colorfilter 27. The first and second transparent substrates 22 and 28 may bemade of tempered glass or a transparent resin.

On outer surfaces of the first and second transparent substrates 22 and28, the first polarizing film 21 and the second polarizing film 29 maybe respectively positioned.

The first polarizing film 21 and the second polarizing film 29 maytransmit specific light and block the other light. For example, thefirst polarizing film 21 may transmit light having a magnetic fieldvibrating in a first direction and block the other light. Also, thesecond polarizing film 29 may transmit light having a magnetic fieldvibrating in a second direction and block the other light, wherein thesecond direction may be orthogonal to the first direction. Accordingly,a polarizing direction of light transmitted by the first polarizing film21 may be orthogonal to a vibration direction of light transmitted bythe second polarizing film 29. As a result, light may be generally nottransmitted through the first polarizing film 21 and the secondpolarizing film 29 simultaneously.

The color filer 27 may be positioned on an inner surface of the secondtransparent substrate 28.

The color filter 27 may include a red filter 27R transmitting red light,a green filter 27G transmitting green light, and a blue filter 27Btransmitting blue light, wherein the red filter 27R, the green filter27G, and the blue filter 27B may be positioned side by side. An area inwhich the color filter 27 is formed may correspond to the pixels Pdescribed above. An area in which the red filter 27R is formed maycorrespond to the red sub pixel P_(R), an area in which the green filter27G is formed may correspond to the green sub pixel P_(G), and an areain which the blue filter 27B is formed may correspond to the blue subpixel P_(B).

On an inner surface of the first transparent substrate 22, the pixelelectrode 23 may be positioned, and on an inner surface of the secondtransparent substrate 28, the common electrode 26 may be positioned.

The pixel electrode 23 and the common electrode 26 may be made of ametal material carrying electricity and may generate an electric fieldfor changing alignment of liquid crystal molecules 25 a configuring theliquid crystal layer 25 which will be described below.

The pixel electrode 23 and the common electrode 26 may be made of atransparent material, and transmit light received from outside. Forexample, the pixel electrode 23 and the common electrode 26 may be madeof Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), an Ag nano wire, acarbon nano tube (CNT), graphene, or 3,4-ethylenedioxythiophene (PEDOT).

On the inner surface of the first transparent substrate 22, the thinfilm transistor 24 may be positioned.

The thin film transistor 24 may transmit or block current flowingthrough the pixel electrode 23. For example, by turning-on (closing) orturning-off (opening) of the thin film transistor 24, an electric fieldmay be formed or removed between the pixel electrode 23 and the commonelectrode 26.

The thin film transistor 24 may be made of poly-silicon and may beformed by a semiconductor process, such as lithography, deposition, ionimplantation, etc.

The liquid crystal layer 25 may be formed between the pixel electrode 23and the common electrode 26, and the liquid crystal layer 25 may befilled with liquid crystal molecules 25 a.

Liquid crystal means an intermediate state between a solid (crystal)state and a liquid state. Most liquid crystal materials are organiccompounds. A molecule of a liquid crystal material is in the shape of athin, long rod. Also, the molecular arrangement of the liquid crystalmaterial is irregular when seen in a specific direction, but appears asa regular crystalloid pattern when seen in another direction.Accordingly, the liquid crystal has both the fluidity of a liquid andthe optical anisotropy of a crystal (solid).

Also, liquid crystal may show an optical property according to a changein electric field. For example, the direction of the moleculararrangement of liquid crystal may change according to a change inelectric field. In the case in which an electric field is formed in theliquid crystal layer 25, liquid crystal molecules 115 a of the liquidcrystal layer 25 may be arranged according to the direction of theelectric field, and in the case in which no electric field is formed inthe liquid crystal layer 25, the liquid crystal molecules 115 a may bearranged irregularly or according to an alignment layer (not shown). Asa result, the optical property of the liquid crystal layer 25 may changeaccording to the presence/absence of an electric field passing throughthe liquid crystal layer 25.

In one edge of the liquid crystal panel 20, a cable 20 a fortransmitting image data to the liquid crystal panel 20, and a displaydriver integrated circuit (hereinafter, referred to as a ‘driver IC’) 30for processing digital image data and outputting an analog image signalmay be positioned.

The cable 20 a may electrically connect the control assembly 50 or thepower supply assembly 60 to the driver IC 30, and also, electricallyconnect the driver IC 30 to the liquid crystal panel 20. The cable 20 amay include a flexible flat cable or a film cable.

The driver IC 30 may receive image data and power from the controlassembly 50 or the power supply assembly 60 through the cable 20 a andmay transmit image data and driving current to the liquid crystal panel20 through the cable 20 a.

Also, the cable 20 a and the driver IC 30 may be implemented as a filmcable, a chip on film (COF), a tape carrier packet (TCP), etc. In otherwords, the driver IC 30 may be positioned on the cable 20 a, although itis not limited thereto. Also, the driver IC 30 may be positioned on theliquid crystal panel 20.

The control assembly 50 may include a control circuit for controllingoperations of the liquid crystal panel 20 and the light source device100. The control circuit may process image data received from anexternal content source, transmit the image data to the liquid crystalpanel 20, and transmit dimming data to the light source device 100.

The power supply assembly 60 may supply power to the liquid crystalpanel 20 and the light source device 100 such that the light sourcedevice 100 outputs surface light. Additionally, the liquid crystal panel20 may block or transmit light emitted from the light source device 100.

The control assembly 50 and the power supply assembly 60 may beimplemented as a printed circuit board with various circuits mounted onthe printed circuit board. For example, a power circuit may include acondenser, a coil, a resistor, a processor, and a power circuit board onwhich they are mounted. Also, a control circuit may include a memory, aprocessor, and a control circuit board on which they are mounted.

Hereinafter, the light source device 100 will be described.

FIG. 4 is an exploded perspective view of a light source deviceaccording to an embodiment of the disclosure. FIG. 5 shows coupling of areflective sheet and a light source module included in a light sourcedevice according to an embodiment of the disclosure.

The light source device 100 may include a light source module 110 forgenerating light, a reflective sheet 120 for reflecting light, adiffuser plate 130 for uniformly diffusing light, and an optical sheet140 for improving brightness of emitted light.

The light source module 110 may include a plurality of light sources 111for emitting light, and a substrate 112 for supporting/fixing theplurality of light sources 111.

The plurality of light sources 111 may be arranged in a preset patternto emit light with uniform brightness. The plurality of light sources111 may be arranged such that distances between a light source and itsneighboring light sources are the same.

For example, as shown in FIG. 4, the plurality of light sources 111 maybe arranged in rows and columns positioned at regular intervals.Accordingly, the plurality of light sources 111 may be arranged suchthat four adjacent light sources have a substantially square shape.Also, a light source may be adjacent to four light sources, and thedistances between the light source and the four adjacent light sourcesmay be substantially the same.

According to another example, the plurality of light sources 111 may bearranged in a plurality of rows, and a light source belonging to eachrow may be positioned on a center line of two light sources belonging toits adjacent row. Accordingly, the plurality of light sources 111 may bearranged such that three adjacent light sources form substantially anequilateral triangle. In this case, a light source may be adjacent tosix light sources, and distances between the light source and the sixlight sources may be substantially the same.

However, an arrangement pattern of the plurality of light sources 111 isnot limited to the above-described patterns, and the plurality of lightsources 111 may be arranged in various patterns as long as the patternsemit light with uniform brightness.

Each light source 111 may adopt a device capable of emitting, uponreceiving power, monochromatic light (light having a specificwavelength, for example, blue light) or white light (mixed light of redlight, green light, and blue light) in various directions. For example,the light source 111 may include a light emitting diode.

The substrate 112 may fix the plurality of light sources 111 such thatthe light sources 111 do not change their positions. Also, the substrate112 may supply power to the individual light sources 111 to enable thelight sources 111 to emit light.

The substrate 112 may be configured with a synthetic resin, temperedglass, or a printed circuit board (PCB), which fixes the plurality oflight sources 111 and on which a conductive power supply line forsupplying power to the light sources 111 is formed.

The reflective sheet 120 may reflect light emitted from the plurality oflight sources 111 in a front direction or in a direction that is closeto the front direction.

In the reflective sheet 120, a plurality of through holes 120 a may beformed at locations respectively corresponding to the plurality of lightsources 111 of the light source module 110. Also, the light sources 111of the light source module 110 may protrude through the through holes120 a in the front direction from the reflective sheet 120.

For example, as shown in an upper part of FIG. 5, the plurality of lightsources 111 of the light source module 110 may be inserted into theplurality of through holes 120 a formed in the reflective sheet 120during a process of assembling the reflective sheet 120 with the lightsource module 110. Accordingly, as shown in a lower part of FIG. 5, thesubstrate 112 of the light source module 110 may be positioned behindthe reflective sheet 120, while the plurality of light sources 111 ofthe light source module 110 may be positioned in front of the reflectivesheet 120.

Accordingly, the plurality of light sources 111 may emit light in frontof the reflective sheet 120.

The plurality of light sources 111 may emit light in various directionsin front of the reflective sheet 120. The light may be emitted from thelight sources 111 toward the reflective sheet 120, as well as toward thediffuser plate 130, and the reflective sheet 120 may reflect the lightemitted toward the reflective sheet 120 toward the diffuser plate 130.

Light emitted from the light sources 111 may pass through variousobjects, such as the diffuser plate 130 and the optical sheet 140. Whileincident light passes through the diffuser plate 130 and the opticalsheet 140, a part of the incident light may be reflected from surfacesof the diffuser plate 130 and the optical sheet 140. The reflectivesheet 120 may reflect light reflected by the diffuser plate 130 and theoptical sheet 140.

The diffuser plate 130 may be positioned in front of the optical module110 and the reflective sheet 120 and uniformly diffuse light emittedfrom the light sources 111 of the light source module 110.

As described above, the plurality of light sources 111 may be positionedat preset locations on a rear surface of the light source device 100.Although the plurality of light sources 111 are arranged at equidistanceintervals on the rear surface of the light source device 100,non-uniformity of brightness may occur according to the positions of theplurality of light sources 111.

The diffuser plate 130 may diffuse light emitted from the plurality oflight sources 111 within the diffuser plate 130 to remove non-uniformityof brightness caused by the plurality of light sources 111. In otherwords, the diffuser plate 130 may uniformly emit non-uniform lightemitted from the plurality of light sources 111 through the frontsurface.

The optical sheet 140 may include various sheets for improvingbrightness and uniformity of brightness. For example, the optical sheet140 may include a diffuser sheet 141, a first prism sheet 142, a secondprism sheet 143, and a reflective polarizing sheet 144.

The diffuser sheet 141 may diffuse light for uniformity of brightness.Light emitted from each light source 111 may be diffused by the diffuserplate 130, and again diffused by the diffusing sheet 141 included in theoptical sheet 140.

The first and second prism sheets 142 and 143 may concentrate the lightdiffused by the diffusing sheet 141 to increase brightness. The firstand second prism sheets 142 and 143 may include a prism pattern being ina shape of a trigonal prism, and a plurality of prism patterns may bearranged to be adjacent to each other, thereby forming a plurality ofbands.

The reflective polarizing sheet 144 may be a kind of a polarizing filmthat transmits a part of incident light and reflects the other portionof the incident light to improve brightness. For example, the reflectivepolarizing sheet 144 may transmit polarized light traveling in a presetpolarization direction of the reflective polarizing sheet 144 andreflect polarized light traveling in a polarization direction that isdifferent from the preset polarization direction of the reflectivepolarizing sheet 144. Also, light reflected by the reflective polarizingsheet 144 may be recycled inside the light source device 100, andbrightness of the display apparatus 10 may be improved by such lightrecycle.

The optical sheet 140 is not limited to the sheets or films shown inFIG. 4, and may include various sheets or films, such as a protectionsheet, etc.

The plurality of light sources 111 mayprotrude through the through holes 120 a from behind the reflectivesheet 120 toward the front direction of the reflective sheet 120.Accordingly, as shown in FIGS. 6 and 7, the light sources 111 and someareas of the substrate 112 may be exposed in the front direction of thereflective sheet 120 through the through holes 120 a.

The light sources 111 may include electrical/mechanical structureslocated at areas defined by the through holes 120 a of the reflectivesheet 120.

Each of the plurality of light sources 111 may include a light emittingdiode 210 and an optical dome 220.

To improve uniformity of surface light emitted by the light sourcedevice 100 and improve a contrast rate by local dimming, the number ofthe light sources 111 may increase. Due to an increase in number of thelight sources 111, an area occupied by each of the plurality of lightsources 111 may become narrow.

To reduce an area occupied by each of the plurality of light sources111, the light source 111 may not include an antistatic circuit (forexample, a Zener diode) for preventing or suppressing the light emittingdiode 210 from being damaged by electrostatic discharge. In other words,the light source 111 may not include a Zener diode connected in parallelwith the light emitting diode 210.

The light emitting diode 210 may include a P-type semiconductor and anN-type semiconductor for emitting light by recombination of holes andelectrons. Also, the light emitting diode 210 may include a pair ofelectrodes 210 a for supplying holes and electrons to the P-typesemiconductor and the N-type semiconductor.

The light emitting diode 210 may convert electrical energy into lightenergy. In other words, the light emitting diode 210 may emit lighthaving a maximum strength in a preset wavelength to which power issupplied. For example, the light emitting diode 210 may emit blue lighthaving a peak value in a wavelength (for example, a wavelength rangingfrom 450 nm to 495 nm) that displays a blue color.

The light emitting diode 210 may be attached directly on the substrate112 by a Chip On Board (COB) method. In other words, the light sources111 may include the light emitting diode 210 in which a light emittingdiode chip or a light emitting diode die is attached directly on thesubstrate 112 without any packaging.

To reduce an area occupied by the light emitting diode 210, the lightemitting diode 210 may be manufactured as a flip chip type including noZener diode. The light emitting diode 210 of the flip chip type may bemanufactured by welding without using an intermediate medium such as ametal lead (wire) or a ball grid array (BGA), upon attaching the lightemitting diode 210 being a semiconductor device onto the substrate 112,an electrode pattern of a semiconductor device as it is on the substrate112.

As such, by omitting a metal lead (wire) or a ball grid array, eachlight source 111 including the light emitting diode 210 of the flip chiptype may be miniaturized.

To miniaturize the light source 111, the light source module 110 inwhich the light emitting diode 210 of the flip chip type is attached onthe substrate 112 by the COB method may be manufactured.

On the substrate 112, a feed line 230 and a feed portion 240 forsupplying power to the light emitting diode 210 of the flip chip typemay be provided.

On the substrate 112, the feed line 230 for supplying an electricalsignal and/or power from the control assembly 50 and/or the power supplyassembly 60 to the light emitting diode 210 may be provided.

As shown in FIG. 8, the substrate 112 may be formed by alternatelystacking an insulation layer 251 having non-conductivity and aconduction layer 252 having conductivity.

On the conduction layer 252, lines or patterns through which powerand/or an electrical signal is transmitted may be formed. The conductionlayer 252 may be formed of various materials having electricalconductivity. For example, the conduction layer 252 may be formed ofvarious metal materials, such as copper (Cu), tin (Sn), aluminum (Al),or an alloy thereof.

A dielectric layer of the insulation layer 251 may insulate between thelines or patterns of the conduction layer 252. The insulation layer 251may be formed of a dielectric for electrical insulation, for example,FR-4.

The feed line 230 may be implemented by the lines or patterns formed onthe conduction layer 252.

The feed line 230 may be electrically connected to the light emittingdiode 210 through the feed portion 240.

The feed portion 240 may be formed by exposing the feed line 230 tooutside.

On an outermost surface of the substrate 112, a protection layer 253 forpreventing the substrate 112 from being damaged by an external impact, achemical action (for example, corrosion, etc.), and/or an optical actionmay be formed. The protection layer 253 may include a Photo SolderResist (PSR).

As shown in FIG. 8, the protection layer 253 may cover the feed line 230to prevent the feed line 230 from being exposed to the outside.

To enable the feed line 230 to electrically contact the light emittingdiode 210, a window for exposing a portion of the feed line 230 to theoutside may be formed in the protection layer 253. The portion of thefeed line 230, exposed to the outside by the window of the protectionlayer 253, may form the feed portion 240.

On the feed portion 240, a conductive adhesive material 240 a may beapplied for an electrical contact of the feed line 230 exposed to theoutside to the electrode 210 a of the light emitting diode 210. Theconductive adhesive material 240 a may be applied in the window of theprotection layer 253.

The electrode 210 a of the light emitting diode 210 may contact theconductive adhesive material 240 a, and the light emitting diode 210 maybe electrically connected to the feed line 230 through the conductiveadhesive material 240 a.

The conductive adhesive material 240 a may include, for example, asolder having electrical conductivity, although it is not limitedthereto. Also, the conductive adhesive material 240 a may includeelectrically conductive epoxy adhesives having electrical conductivity.

Power may be supplied to the light emitting diode 210 through the feedline 230 and the feed portion 240, and the light emitting diode 210 mayreceive the power to emit light. A pair of feed portions 240respectively corresponding to the pair of electrodes 210 a included inthe light emitting diode 210 of the flip chip type may be provided.

The optical dome 220 may cover the light emitting diode 210. The opticaldome 220 may prevent or suppress the light emitting diode 210 from beingdamaged by an external mechanical action and/or by a chemical action.

The optical dome 220 may be in a shape of a dome resulting from cutting,for example, a sphere with a plane not including a center of the sphere,or in a shape of a hemisphere resulting from cutting a sphere with aplane including a center of the sphere. A vertical section of theoptical dome 220 may be in a shape of, for example, a segment of acircle or a semicircle.

The optical dome 220 may be formed of silicon or an epoxy resin. Forexample, the optical dome 220 may be formed by discharging moltensilicon or a molten epoxy resin onto the light emitting diode 210through a nozzle, etc. and then hardening the discharged silicon orepoxy resin.

Accordingly, the optical dome 220 may have various shapes according toviscosity of liquid silicon or an epoxy resin. For example, in the casein which the optical dome 220 is manufactured with silicon having athixotropic index of about 2.7 to about 3.3 (preferably, 3.0), theoptical dome 220 may have a dome ratio of about 2.5 to about 3.1(preferably, 2.8), wherein the dome ratio represents a ratio (the heightof the dome/the diameter of the base side of the dome) of a height ofthe dome with respect to a diameter of a base side of the dome. Forexample, a diameter of the base side of the optical dome 220manufactured with silicon having a thixotropic index of about 2.7 toabout 3.3 (preferably, 3.3) may be about 2.5 mm, and a height of theoptical dome 220 may be about 0.7 mm.

The optical dome 220 may be optically transparent or translucent. Lightemitted from the light emitting diode 210 may pass through the opticaldome 220 and be emitted to the outside.

At this time, the optical dome 220 being in a shape of a dome mayrefract the light, like a lens. For example, light emitted from thelight emitting diode 210 may be refracted by the optical dome 220 anddispersed.

As such, the optical dome 220 may protect the light emitting diode 210from an external mechanical action, chemical action, and/or electricalaction, and disperse light emitted from the light emitting diode 210.

Around the optical dome 220, an antistatic member 260 for protecting thelight emitting diode 210 from electrostatic discharge may be formed.

The antistatic member 260 may absorb an electrical impact caused byelectrostatic discharge generated around the optical dome 220.

As described above, the optical dome 220 may protect the light emittingdiode 210 from an external electrical action. Charges generated byelectrostatic discharge may not pass through the optical dome 220 andmay flow along an outer surface of the optical dome 220. The chargesflowing along the outer surface of the optical dome 220 may arrive atthe light emitting diode 210 along a boundary between the optical dome220 and the substrate 112. The light emitting diode 210 may be damagedby an electrical impact caused by the charges permeated along theboundary between the optical dome 220 and the substrate 112. To preventor suppress such a flow of charges (i.e. current), the antistatic member260 may be provided around the optical dome 220.

The antistatic member 260 may include an antistatic line 270 and anantistatic portion 280.

The antistatic line 270 may provide a path of current caused byelectrostatic discharge generated around the optical dome 220. In otherwords, the antistatic line 270 may guide charges generated byelectrostatic discharge to flow to the ground. The antistatic line 270may be formed of the same material as the feed line 230. For example,the antistatic line 270 may be formed of various metal materials, suchas copper (Cu), tin (Sn), aluminum (Al), or an alloy thereof.

For example, the substrate 112 may be formed by alternately stacking theinsulation layer 251 having non-conductivity and the conduction layer252 having conductivity. The conduction layer 252 may be formed ofvarious metal materials, such as copper (Cu), tin (Sn), aluminum (Al),or an alloy thereof.

The antistatic line 270 may be implemented by a line or pattern formedon the conduction layer 272.

As described in FIG. 9, the antistatic line 270 may be exposed to theoutside through the antistatic portion 280.

The protection layer 253 may cover the antistatic line 270 to preventthe antistatic line 270 from being exposed to the outside. In theprotection layer 253, a window may be formed to form the antistaticportion 280 for capturing current generated by electrostatic discharge.The antistatic line 270 may be exposed to the outside by the window ofthe protection layer 253, and a portion of the antistatic line 270exposed to the outside may form the antistatic portion 280.

As such, the antistatic portion 280 may be formed by exposing a portionof the antistatic line 270 to the outside. The antistatic portion 280may be provided separately from the feed portion 240 contacting thelight emitting diode 210, and the antistatic portion 280 may not contactthe light emitting diode 210.

As shown in FIG. 10, the antistatic portion 280 may include a firstantistatic portion 281 and a second antistatic portion 282. The firstantistatic portion 281 and the second antistatic portion 282 may bepositioned to both sides of the optical dome 220.

The first antistatic portion 281 and the second antistatic portion 282may be maximally spaced from each other on a circumference of an virtualcircle surrounding the light source 111. For example, the firstantistatic portion 281 and the second antistatic portion 282 may bepositioned to form an angle of about 180 degrees with respect to eachother along a circumference of an virtual circle surrounding the opticaldome 220.

However, an arrangement of the first antistatic portion 281 and thesecond antistatic portion 282 is not limited to that shown in FIG. 10,and the first antistatic portion 281 and the second antistatic portion282 may have any arrangement capable of preventing or suppressingcurrent caused by electrostatic discharge from flowing to the lightemitting diode 210 along the feed line 230 or the boundary between theoptical dome 220 and the substrate 112. For example, the firstantistatic portion 281 and the second antistatic portion 282 may bearranged to form an angle of about 90 degrees or 120 degrees withrespect to each other along a circumference of an virtual circlesurrounding the optical dome 220.

A size of the antistatic portion 280 may depend on various factors. Forexample, a large size of the antistatic portion 280 may increase apotential difference capable of preventing or suppressing currentgenerated by electrostatic discharge from flowing to the light emittingdiode 210. In other words, as the size of the antistatic portion 280increases, antistatic performance of the antistatic portion 280 may beimproved.

Meanwhile, as the size of the antistatic portion 280 increases, opticalinterference of the antistatic portion 280 may increase accordingly. Forexample, in the case in which the antistatic portion 270 is formed ofcopper, the antistatic portion 280 may have an intrinsic color (forexample, brown) of copper. In this case, monochromatic light (forexample, blue light) emitted from the light source 111 may be reflectedfrom the antistatic portion 280.

While the monochromatic light is reflected from the antistatic portion280, the intrinsic color of the antistatic portion 280 may be added. Forexample, monochromatic light emitted from the light source 111 may beblue light having a peak value in a wavelength range from 450 nm to 495nm. In this case, a spectrum of light reflected from the antistaticportion 280 may have a plurality of peaks, and at least some of theplurality of peaks may deviate from the wavelength range from 450 nm to495 nm. In other words, due to the antistatic portion 280, light havinga peak deviating from the wavelength range of monochromatic light may beemitted.

As such, due to the antistatic portion 280, a spectrum of light emittedfrom the light source 111 may be distorted, which may reduce a colorgamut of the display apparatus 10. Furthermore, the distortion of thespectrum of light emitted from the light source 111 may cause a mura(unevenness) phenomenon.

Accordingly, the size of the antistatic portion 280 may be determined byconsidering antistatic performance and a color distortion.

The size of the antistatic portion 280 determined by consideringantistatic performance may depend on a size of the optical dome 220.

A ratio of an area of the antistatic portion 280 to an area of the baseside of the optical dome 220 may be preferably at least 1:0.0016 ormore. In the case in which a diameter of the base side of the opticaldome 220 is 2.5 mm (a radius of 1250 μm and an area of about 4,900,000μm²), an area of the antistatic portion 280 may be about 7,900 μm² ormore. In the case in which the antistatic portion 280 is in a shape of acircle, a diameter of the antistatic portion 280 may be about 50 μm ormore. Also, in the case in which the antistatic portion 280 is in ashape of a square, a length of a side of the antistatic portion 280 maybe about 90 um or more. For example, the area of the antistatic portion280 may be preferably about 62,500 μm² (a ratio of the area of theantistatic portion 280 to the area of the base side of the optical dome220 is about 1:0.013). In the case in which the antistatic portion 280is in a shape of a circle, a diameter of the antistatic portion 280 maybe preferably about 140 μm. Also, in the case in which the antistaticportion 280 is in a shape of a square, a length of a side of theantistatic portion 280 may be preferably about 250 μm.

The above-described ratios are examples of a ratio of an area of theantistatic portion 280 to an area of the base side of the optical dome220, and a ratio of an area of the antistatic portion 280 to an area ofthe base side of the optical dome 220 is not limited to theabove-described examples.

A location (a distance to the optical dome 220) of the antistaticportion 280, which is determined by considering antistatic performance,may depend on the size of the optical dome 220.

The antistatic portion 280 may have higher antistatic performance at acloser distance to the outer surface of the optical dome 220. However,in the case in which the antistatic portion 280 is positioned to theinner side from the outer surface of the optical dome 220, opticalinterference may occur. Accordingly, the antistatic portion 280 may bepreferably positioned to the outer side from an outline of the opticaldome 220. At least one portion of the antistatic portion 280 may bepreferably exposed outside an area defined by the optical dome 220.

Also, to prevent or suppress charges generated by electrostaticdischarge from arriving at the feed portion 240, it may be preferablethat a shortest distance from the outline of the optical dome 220 to theantistatic portion 280 is shorter than a shortest distance from theoutline of the optical dome 220 to the feed portion 240.

The shortest distance from the outline of the optical dome 220 to theantistatic portion 280 may be shorter than a radius of the optical dome220. In the case in which the diameter of the base side of the opticaldome 220 is 2.5 mm (in the case in which the radius of the optical dome220 is 1250 μm), a distance from the outline of the optical dome 220 tothe antistatic portion 280 may be about 1250 μmm or less. For example, ashortest distance from the outline of the optical dome 220 to theantistatic portion 280 may be preferably 500 μm or less.

Equivalent circuits of the light source 111 including the light emittingdiode 210 and the antistatic member 260 are shown in FIGS. 11A and 11B.

The light emitting diode 210 may be electrically connected to the feedline 230 through the feed portion 240, and the first and secondantistatic portions 281 and 282 may be positioned around the lightemitting diode 210.

As shown in (a) of FIG. 11, the first and second antistatic portions 281and 282 may be connected to the ground by the antistatic line 270.Charges captured by the first and second antistatic portions 281 and 282may flow to the ground along the antistatic line 270.

Also, as shown in (b) of FIG. 11, the antistatic line 270 connected tothe first and second antistatic portions 281 and 282 may be coupled withthe ground by parasitic capacitance, without being directly connected tothe ground. Charges captured by the first and second antistatic portions281 and 282 may flow to the ground by the parasitic capacitance alongthe antistatic line 270.

By the antistatic member 260, electrostatic discharge tolerance of thelight source 111 may be improved.

For example, as shown in FIG. 12, in the case in which an object COcharged with negative charges approaches or contacts the light source111, the negative charges may be emitted from the charged object CO.

The emitted negative charges may not pass through the inside of theoptical dome 220 made of a non-conductive material, and may move alongthe outer surface of the optical dome 220.

The negative charges moving along the outer surface of the optical dome220 may move to the antistatic portion 280 along the outer surface ofthe substrate 112 at the boundary of the optical dome 220 and thesubstrate 112, or move to the feed portion 240 along the boundary of theoptical dome 220 and the substrate 112.

In the case in which the antistatic portion 280 is located close to theouter surface of the optical dome 220, a large portion of the negativecharges may move to the antistatic portion 280, and an extremely smallportion of the negative charges may move to the feed portion 240. Inother words, current generated by electrostatic discharge may flow tothe ground through the antistatic portion 280, and extremely smallcurrent may flow to the light emitting diode 210 through the feedportion 240.

Therefore, the electrostatic discharge tolerance of the light source 111may be improved. In other words, a voltage caused by electrostaticdischarge, which the light source 111 is capable of tolerating, mayincrease.

According to an experiment, electrostatic discharge tolerance of a lightsource having an optical dome of which the diameter of the base side is2.5 mm and of which the height is 0.7 mm was measured as about 3 kV.Meanwhile, in the case in which an antistatic portion of 0.5 mm*0.5 mm(width*height) is positioned within 0.5 mm from an optical dome havingthe same size, electrostatic discharge tolerance of the correspondinglight source was improved to about 10 kV.

An arrangement and shape of the antistatic portion 280 for improving theelectrostatic discharge tolerance of the light source 111 may vary.

Hereinafter, various arrangements and shapes of the antistatic portion280 will be described.

FIG. 13 shows a light source including an antistatic portion, accordingto an embodiment of the disclosure. FIG. 14 shows a light sourceincluding three or more antistatic portions, according to an embodimentof the disclosure.

FIGS. 6 and 10 show the first and second antistatic portions 281 and 282positioned around the light source 111, however, the number of theantistatic portion 280 is not limited to that shown in FIGS. 6 and 10.

For example, as shown in FIG. 13, the antistatic member 260 may includea third antistatic portion 283 positioned around the light source 111. Astructure (side cross-section) and shape of the third antistatic portion283 may be the same as those of the first and second antistatic portions281 and 282 shown in FIGS. 6 and 10.

The third antistatic portion 283 may be positioned in a direction inwhich electrostatic discharge mainly occurs.

For example, in the case in which electrostatic discharge frequentlyoccurs at a specific location of the light source device 100, the thirdantistatic portion 283 may be positioned toward the specific location.In other words, the third antistatic portion 283 may be positionedcloser to the specific location than the light emitting diode 210 of thelight source 111 and/or the feed portion 240.

Also, in the case in which electrostatic discharge more frequentlyoccurs at an outer portion of the light source device 100 than at acenter portion of the light source device 100, the antistatic portion280 may be positioned closer to the outer portion of the light sourcedevice 100 than the light emitting diode 210 of the light source 111and/or the feed portion 240.

Therefore, because of the positioning of the third antistatic portion283, the antistatic member 260 may protect the light emitting diode 210from electrostatic discharge frequently occurring at a specificlocation.

In addition, by reducing the number of the antistatic portion 280,optical interference that is generated by the intrinsic color of theantistatic portion 280 may be reduced. Accordingly, a distortion incolor of light emitted from the light source device 100 may be reduced.

Also, as shown in FIG. 14, the antistatic member 260 may include threeor more fourth antistatic portions 284 a, 284 b, and 284 c providedaround the light source 111. A structure and shape of each of the threeor more fourth antistatic portions 284 a, 284 b, and 284 c may be thesame as those of the first and second antistatic portions 281 and 282described above.

The three or more fourth antistatic portions 284 a, 284 b, and 284 c maysurround the optical dome 220.

The three or more fourth antistatic portions 284 a, 284 b, and 284 c maybe maximally spaced from each other on a circumference of a virtualcircle surrounding the optical dome 220. For example, the three or morefourth antistatic portions 284 a, 284 b, and 284 c may be positioned atsubstantially equidistant intervals along the circumference of thevirtual circle surrounding the optical dome 220. The three fourthantistatic portions 284 a, 284 b, and 284 c may be positioned to form anangle of about 120 degrees with respect to each other along thecircumference of the virtual circle surrounding the optical dome 220.Also, as shown in FIG. 14, six antistatic portions may be positioned toform an angle of about 60 degrees with respect to each other along thecircumference of the virtual circle surrounding the optical dome 220. Inthis case, the light emitting diode 210 and/or the feed portion 240 maybe positioned at a center of the virtual circle surrounding the opticaldome 220.

Because the three or more fourth antistatic portions 284 a, 284 b, and284 c are positioned around the optical dome 220, the antistatic member260 may protect the light emitting diode 210 from electrostaticdischarge generated in substantially all directions with respect to theoptical dome 220. In other words, because the three or more fourthantistatic portions 284 a, 284 b, and 284 c are positioned around theoptical dome 220, distances from a location at which electrostaticdischarge occurs on the outer surface of the optical dome 220 to thethree or more fourth antistatic portions 284 a, 284 b, and 284 c may bereduced. Therefore, a portion of electrostatic discharged chargescaptured by the three or more fourth antistatic portions 284 a, 284 b,and 284 c may further increase, and the electrostatic dischargetolerance of the light source 111 may be further improved.

Optical interference caused by the three or more fourth antistaticportions 284 a, 284 b, and 284 c may be removed by reducing sizes of thethree or more fourth antistatic portions 284 a, 284 b, and 284 c. Inother words, the sizes of the three or more fourth antistatic portions284 a, 284 b, and 284 c may be reduced such that a total area of thethree or more fourth antistatic portions 284 a, 284 b, and 284 c becomesa preset area.

FIG. 15 shows a light source including an antistatic portion being in ashape of a circle, according to an embodiment of the disclosure. FIG. 16shows a light source including an antistatic portion being in a shape ofan arc, according to an embodiment of the disclosure.

FIGS. 6 and 10 show the first and second antistatic portions 281 and 282each being in a shape of substantially a rectangle, however, the shapeof the antistatic portion 280 is not limited to that shown in FIGS. 6and 10.

For example, as shown in FIG. 15, the antistatic member 260 may includefifth and sixth antistatic portions 285 and 286 each being in a shape ofsubstantially a circle. Structures (side cross-sections) of the fifthand sixth antistatic portions 285 and 286 being in the shape of thecircle may be the same as those of the first and second antistaticportions 281 and 282 shown in FIGS. 6 and 10.

Because a circular antistatic portion has no directivity, the fifth andsixth antistatic portions 285 and 286 may easily capture chargesgenerated by electrostatic discharge occurred around the fifth and sixthantistatic portions 285 and 286.

The shape of the antistatic portion 280 is not limited to a rectangleand a circle. For example, the shape of the antistatic portion 280 maybe a polygon including a triangle, a rectangle, a pentagon, a hexagon,etc. Also, the shape of the antistatic portion 280 may be a circle, anoval, a semicircle, a segment of a circle, etc.

Also, as shown in FIG. 16, the antistatic member 260 may include seventhand eighth antistatic portions 287 and 288 each being in a shape ofsubstantially an arc, which surround the optical dome 220.

A structure (side cross-section) of the antistatic portion 280 being inthe shape of the arc may be the same as those of the first and secondantistatic portions 281 and 282 shown in FIGS. 6 and 10.

Unlike the three or more fourth antistatic portions 284 a, 284 b, and284 c arranged at substantially equidistant intervals on thecircumference of the virtual circle surrounding the optical dome 220,each of the seventh and eighth antistatic portions 287 and 288 shown inFIG. 16 may be in a shape of an arc of an virtual circle surrounding theoptical dome 220.

Because the seventh and eighth antistatic portions 287 and 288 being inthe shape of the arc surrounding the optical dome 220 are provided, thelight emitting diode 210 may be protected from electrostatic dischargeoccurring in all directions with respect to the optical dome 220. Inother words, because the seventh and eighth antistatic portions 287 and288 being in the shape of the arc are positioned around the optical dome220, distances from a location at which electrostatic discharge occurson the outer surface of the optical dome 220 to the seventh and eighthantistatic portions 287 and 288 may be greatly reduced. Therefore, aportion of electrostatic discharged charges captured by the seventh andeighth antistatic portions 287 and 288 may further increase, and theelectrostatic discharge tolerance of the light source 111 may be furtherimproved.

However, the shape of the antistatic portion 280 is not limited to anarc shape, and the antistatic portion 280 may be in a shape of a ring.In other words, the antistatic portion 280 may be in a shape of a ringsurrounding the optical dome 220.

FIG. 17 shows a light source including an antistatic portion of which aportion overlaps with an optical dome, according to an embodiment of thedisclosure. FIG. 18 shows a light source including an antistatic portionoverlapping with an optical dome and an antistatic portion notoverlapping with the optical dome, according to an embodiment of thedisclosure. FIG. 19 shows a light source including an antistatic portionoverlapping with an optical dome and an antistatic portion notoverlapping with the optical dome, according to an embodiment of thedisclosure. FIG. 20 shows a light source including three or moreantistatic portions overlapping with an optical dome and three or moreantistatic portions not overlapping with the optical dome, according toan embodiment of the disclosure. FIG. 21 shows a light source includingthree or more antistatic portions of which portions overlap with anoptical dome, according to an embodiment of the disclosure.

FIGS. 6 and 10 shows the first and second antistatic portions 281 and282 not overlapping with the optical dome 220, and a relativearrangement of the optical dome 220 and the antistatic portion 280 isnot limited to the arrangement shown in FIGS. 6 and 10.

For example, as shown in FIG. 17, the antistatic member 260 may includeninth and tenth antistatic portion 289 and 290 of which portions overlapwith the optical dome 220. Structures (side cross-sections) of the ninthand tenth antistatic portions 289 and 290 may be the same as those ofthe first and second antistatic portions 281 and 282 shown in FIGS. 6and 10.

The ninth and tenth antistatic portions 289 and 290 of which portionsoverlap with the optical dome 220 may be positioned at an area at whichthe outer surface of the optical dome 220 crosses the substrate 112. Asdescribed above, charges generated by electrostatic discharge may moveto the boundary between the optical dome 220 and the substrate 112 alongthe outer surface of the optical dome 220. Because the ninth and tenthantistatic portions 289 and 290 are positioned at the boundary betweenthe outer surface of the optical dome 220 and the substrate 112, chargesmoving along the outer surface of the optical dome 220 may move to theninth and tenth antistatic portions 289 and 290. Accordingly, aprobability that charges moving along the outer surface of the opticaldome 220 will be captured by the antistatic member 260 may furtherincrease. Also, the antistatic performance of the antistatic member 260may be improved, and the electrostatic discharge tolerance of the lightsource 111 may be improved.

Also, as shown in FIG. 18, the antistatic member 260 may include thefirst and second antistatic portions 281 and 282 positioned outside theouter surface of the optical dome 220, and eleventh and twelfthantistatic portions 291 and 292 positioned to the inner side from theouter surface of the optical dome 220. Structures (side cross-sections)and shapes of the ninth and twelfth antistatic portions 291 and 292 maybe the same as those of the first and second antistatic portions 281 and282 shown in FIGS. 6 and 10.

As described above, the first and second antistatic portions 281 and 282may capture charges moving outward from the outer surface of the opticaldome 220. Also, the eleventh and twelfth antistatic portions 291 and 292may capture charges moving inward from the outer surface of the opticaldome 220 along the boundary between the optical dome 220 and thesubstrate 112.

Accordingly, the antistatic member 260 including the antistatic portions281, 282, 291, and 292 positioned to the outer and inner sides from theouter surface of the optical dome 220 may capture a major portion ofcharges generated by electrostatic discharge. Accordingly, theantistatic performance of the antistatic member 260 may be improved, andthe electrostatic discharge tolerance of the light source 111 may beimproved.

As shown in FIG. 19, the antistatic member 260 may include the thirdantistatic portion 283 positioned to the outer side from the outersurface of the optical dome 220, and a thirteenth antistatic portion 293positioned to the inner side from the outer surface of the optical dome220. A structure (side cross-section) and shape of the thirteenthantistatic portion 293 may be the same as those of the first and secondantistatic portions 281 and 282 shown in FIGS. 6 and 10.

By minimizing the number of the antistatic portions, opticalinterference due to the intrinsic color of the antistatic portion 280may be reduced. Accordingly, a distortion in color of light emitted fromthe light source device 100 may be reduced.

As shown in FIG. 20, the antistatic member 260 may include the three ormore fourth antistatic portions 284 a, 284 b, and 284 c positionedoutside the light source 111, and three or more fourteenth antistaticportions 294 a, 294 b, and 294 c positioned inside the light source 111.Structures and shapes of the three or more fourth antistatic portions284 a, 284 b, and 284 c and the three or more fourteenth antistaticportions 294 a, 294 b, and 294 c may be the same as those of the firstand second antistatic portions 281 and 282 described above.

The three or more fourth antistatic portions 284 a, 284 b, and 284 c maysurround the optical dome 220. The three or more fourteenth antistaticportions 294 a, 294 b, and 294 c may surround the light emitting diode210 and the feed portion 240. An arrangement of the three or more fourthantistatic portions 284 a, 284 b, and 284 c may be the same as that ofthe three or more fourth antistatic portions 284 a, 284 b, and 284 cshown in FIG. 14.

The three or more fourteenth antistatic portions 294 a, 294 b, and 294 cmay be arranged on a circumference of an virtual circle surrounding thelight emitting diode 210 and the feed portion 240, and maximally spacedfrom each other on the circumference of the virtual circle. For example,the three or more fourteenth antistatic portions 294 a, 294 b, and 294 cmay be arranged at substantially equidistant intervals along thecircumference of the virtual circle surrounding the light emitting diode210 and the feed portion 240. Six antistatic portions as shown in FIG.20 may be arranged to form an angle of about 60 degrees with respect toeach other along the circumference of the virtual circle surrounding thelight emitting diode 210 and the feed portion 240.

Because the three or more fourteenth antistatic portions 294 a, 294 b,and 294 c are provided inside the optical dome 220, the antistaticmember 260 may capture charges generated by electrostatic discharge insubstantially all directions, the charges being permeated into theinside of the optical dome 220. Therefore, a portion of electrostaticdischarged charges captured by the antistatic member 260 may furtherincrease, and the electrostatic discharge tolerance of the light source111 may be further improved.

As shown in FIG. 21, the antistatic member 260 may include three or morefifteenth antistatic portions 295 a, 295 b, and 295 c of which portionsoverlap with the optical dome 220. Structures and shapes of the three ormore fifteenth antistatic portions 295 a, 295 b, and 295 c may be thesame as those of the first and second antistatic portions 281 and 282described above.

The three or more fifteenth antistatic portions 295 a, 295 b, and 295 cmay be arranged on a circumference of an virtual circle corresponding toan outermost portion of the optical dome 220, and maximally spaced fromeach other on the circumference of the virtual circle. For example, thethree or more fifteenth antistatic portions 295 a, 295 b, and 295 c maybe arranged at substantially equidistant intervals along the outermostportion of the optical dome 220.

Because the three or more fifteenth antistatic portions 295 a, 295 b,and 295 c of which portions overlap with the optical dome 220 areprovided, the antistatic member 260 may capture charges generated byelectrostatic discharge in substantially all directions, the chargesbeing permeated into the inside of the optical dome 220. Therefore, aportion of electrostatic discharged charges captured by the antistaticmember 260 may further increase, and the electrostatic dischargetolerance of the light source 111 may be further improved.

As described above, the antistatic portion 280 for protecting the lightemitting diode 210 from electrostatic discharge may be in variousnumbers, shapes, and arrangements as necessary.

Also, the structure (side cross-section) of the antistatic portion 280is also not limited to that shown in FIG. 9, and the antistatic portion280 may be formed with various structures.

FIG. 22 shows a light source including an antistatic portion forprotecting a feed line, according to an embodiment of the disclosure.

As shown in FIG. 22, the antistatic member 260 may include the first andsecond antistatic portions 281 and 282 arranged around the optical dome220, and sixteenth antistatic portions 296 a and 296 b and seventeenthantistatic portions 297 a and 297 b arranged around the feed line 230.Structures (side cross-sections) and shapes of the sixteenth andseventeenth antistatic portions 296 a, 296 b, 297 c, and 297 b may bethe same as those of the first and second antistatic portions 281 and282 shown in FIGS. 6 and 10.

The first and second antistatic portions 281 and 282 may capture chargesmoving outward from the outer surface of the optical dome 220.

The protection layer 253 may be configured generally with an insulator,and protect a feed circuit such as the feed line 230 from electrostaticdischarge. However, because the protection layer 253 has a thinthickness compared to the optical dome 220, the protection layer 253 mayhave a lower voltage level capable of protecting the feed circuit suchas the feed line 230 from electrostatic discharge than the optical dome220. Accordingly, charges may permeate into the feed line 230 byelectrostatic discharge generated around the feed line 230, and thecharges may damage the light emitting diode 210 via the feed line 230.

To prevent or suppress permeation of charges through the feed line 230,the sixteenth and seventeenth antistatic portions 296 a, 296 b, 297 a,and 297 b may be provided around the feed line 230. As shown in FIG. 22,the sixteenth antistatic portions 296 a and 296 b may be arranged toboth sides of the feed line 230 along the feed line 230. The seventeenthantistatic portions 297 a and 297 b may be also arranged to both sidesof the feed line 230 along the feed line 230.

Due to the sixteenth and seventeenth antistatic portions 296 a, 296 b,297 a, and 297 b, the light emitting diode 210 may be prevented orsuppressed from being damaged by electrostatic discharge generatedaround the feed line 230.

FIG. 23 shows another example of a side cross-section of the lightsource shown in FIG. 6, taken in the B-B′ direction of FIG. 6.

As shown in FIG. 23, the protection layer 253 may cover the antistaticline 270 to prevent the antistatic line 270 from being exposed to theoutside. Herein, a window for forming the antistatic portion 280 forcapturing current generated by electrostatic discharge may be formed inthe protection layer 253. As such, the antistatic line 270 may beexposed to the outside through the antistatic portion 280.

A conductive adhesive material 280 a may be applied on the antistaticportion 280. The conductive adhesive material 280 a may be applied inthe window of the protection layer 253.

The conductive adhesive material 280 a may include a solder havingelectrical conductivity. The solder is known to have high lightreflectivity.

Because the conductive adhesive material 280 a having high lightreflectivity is applied on the antistatic portion 280, opticalinterference that is caused by the antistatic line 270 exposed throughthe antistatic portion 280 may be reduced. In other words, a spectrum oflight emitted from the light source 111 may be prevented or suppressedfrom being distorted by a color of the antistatic portion 280 formedwith copper.

Accordingly, an area of the antistatic portion 280 may be enlargedwithout causing the mura (unevenness) phenomenon.

FIG. 24 shows another example of a side cross-section of the lightsource shown in FIG. 6, taken in the B-B′ direction of FIG. 6.

As shown in FIG. 24, the protection layer 253 may cover the antistaticline 270 to prevent the antistatic line 270 from being exposed to theoutside. Herein, in the protection layer 253, a via-hole 270 a may beformed to form the antistatic portion 280 for capturing currentgenerated by electrostatic discharge. The antistatic portion 280 may beformed on the protection layer 253, and the antistatic portion 280 maybe electrically connected to the antistatic line 270 through thevia-hole 280 a of the protection layer 253.

As such, because the antistatic portion 280 is formed on the protectionlayer 253, performance of the antistatic member 260 of capturing chargesgenerated by electrostatic discharge may be improved. Accordingly, theelectrostatic discharge tolerance of the light source 111 may be furtherimproved.
